Email is still the number one concern for security leaders, while threat actors consider it one of the easiest ways to infiltrate organizations. The FBI has received over 250,000 business email compromise (BEC) reports in the past decade, with phishing or BEC attacks costing organizations an average of $4.5 million per breach.
If you think your rule-based email security solution offers sufficient protection, think again. Sophisticated threat actors are sidestepping these traditional email security controls with advanced attack techniques (e.g., QR code scams and image-based attacks.) Organizations must move beyond secure email gateways to stay ahead of emerging threats — but how?
Implement an email security tool with advanced AI-driven threat detection to identify suspicious emails through behavioral, content, and threat network analysis. It should integrate with your existing email platform, like Microsoft or Google, to ensure fast and seamless deployment.
That’s why more companies choose Tessian to augment their defense with the latest behavioral analytics and AI capabilities. Let’s look at why Tessian and Microsoft 365 are better together.
Tessian x Microsoft: Supercharge email security with a layered defense
Microsoft’s Exchange Online Protection and Defender solutions filter spam, catch malware, and perform URL inspection. But often, sophisticated attacks fall through the cracks.
Tessian adds AI-driven capabilities to augment defense and provide contextual warnings to help users stop BEC, impersonation, spoofing, invoice and payment fraud, and account takeover. Additionally, Tessian complements Microsoft Purview to prevent misdirected emails and stop email data exfiltration.
3 Reasons to boost M365 security with Tessian
In our recent webinar, we caught up with Steve Wingate, a CISO in the healthcare industry, on how Tessian helped strengthen email security while reducing the cost and complexity of the security stack:
1. Improve efficacy against advanced threats
Traditional rule-based email security solutions rely on detecting known bad, rendering them potentially ineffective against new techniques. On the other hand, Tessian’s behavioral, content, and threat network analytics can adapt to emerging threats as they evolve.
Wingate decided to use Tessian because secure email gateways couldn’t provide enough protection. A good developer can easily bypass them and attack an SMTP server directly. Microsoft’s gateway caught only 25% of email threats — exposing his company to various BEC, spoofing, and spam emails.
Moreover, the rise of generative AI allows threat actors to augment their social engineering and phishing techniques — it’s time to use AI to fight AI.
2. Enhance security team productivity
Before using Tessian, Wingate’s team received over 1,200 phishing reports per month without sufficient controls to manage potential threats.
Tessian helps them streamline workflows, minimize human intervention, and save time on email security — with lightning fast search and advanced search queries .
With Tessian, their team saved 2 to 3 hours daily on triaging and investigating emails. With these time savings, now they could spend more time on proactive measures and focus on strategic priorities.
3. Coach end-users in the moment
For many cybersecurity professionals, end-users are often the weakest link. After all, it takes only one person to click on one malicious email to infect the entire system or put the wrong recipient in an email to exfiltrate sensitive information.
But providing security training during new hire onboarding is like making them drink from a firehose — it’s impossible to retain all the information. On the other hand, Tessian helps you coach users and educate them on email risks in real-time with contextualized and user-friendly banners.
After using Tessian, Wingate found that new users were 22% less likely to fail a phishing test and 38% more likely to report a phishing email. Tessian helped turn end-users into an extension of his security team and foster a security culture in his organization.
